This plastic ball lock cap features soda bottle threads, allowing you to convert a soda bottle into a pressurizable growler. It is compatible with both gas and liquid ball lock disconnects. Also works well for cleaning draft lines. Simply add line cleaning solution to a soda bottle, attach it to the draft line, and open the faucet to push solution through.
This cap can also be attached to the FermZilla collection container, enabling you to purge the collection container of oxygen.
The barb is Duotight compatible. If you'd like to use the cap with 8 mm OD EVABarrier tubing, see DUO100.
